SIGHTING-TYELESCOIEE Application filed March a, 1910. Serial 1x04547 46.i

LER and ALBERT Geese, both of Rochester? in the ceun-ty of Monroe, Stateof New York, have invented certain new and useful Im- -V provements-inSighting-Telescopes; and We do hereby declare tl clear, andexact descrrp 'locat ollowing to bee. full, ion of the vsame, reference h-eing hadto the accompanying draw ings, to .ning a part of thisspecificationgiand to the reference-numerals marked thereon.

The present invention relates to' sighting telescopes and it has or anobject to provide aconstruction adapted for use with. guns ed within arestricted space, such for instants as in the turret of a war ship.

A further object is to construct the parts so that they willnot bedisplaced nor have their adjustments destroyed by the vibrationsorjarsdue to the tiring of the gun.

A still furtherobject is to provide a construction in which the crosshairs or sighting n "it may be rotated in order that the instrument maybe shifted relatively to the gun.

To these and other ends the invention consists in certain improvementsand combinations of parts all as will be hereinafter more fullydescribed, the novel features being pointed out in the claims at the endof the specification. p

In the drawings: Figure lshows an -exterior view of an instrumentconstructed in accordance with this invention and havin a supportingbracket connectedthereto; Fig. 2 shows, in full lines and in dottedlines, two different positionsto which the instrument is capable ofbeing shifted; Fig. 8 is an axial section of the instrument in proximityto the telescope in proximity to the eye piece;

Fig. 8 is a section onlthe line b-b of Fig. 7,

and Figs. 9 and 10 are sections on the linec-c of Fig. 7, showing thecross hairs or sighting mark at its two limits of ad ustment.

Int-he turret ot a' warship the space is so restricted that itisundesirable to use an ordinary telescope with a straight casing and ithas been customary to employ one having a casing of angular formation sothat the eyepiece may lie to one: side of the gun as usual while the"objective may be disposed at'any convenient place. In such telescopesthe cros hairs or sighting mark has been arranged with reference to thep sition of the instrument so that one cross may lie verticalwliile theother is horizon-- tal. Therefore; when, as has been the case, it wasdesired to change the position of the usual instrument to the oppositesideot' the gun the cross hairs do not lie in the properv me nest. as,item.

positions. In this invention provision, has i been made wherebythe-cross hairs or sighting mark may 'be shitted or; rotated in itsplane so that the basing pf the in trument may be placed in anypositionr There has also, been provided afcons'ti'uctijon in which thepositions of the optical parts (lenses and reflectors) are held firmlyin position against the vibrations produced in tiring the gun, and tl1eS9VI1l adjustments have also been constructed so that'they will not beattected by the vibrations. Provision has also been made whereby thecasing of the telescope may be adapted forfirmengagement by a supportsothat vibrationsin the latter will not take place.

In the present embodiment of the inven tion herein illustrated theinstrument is pro-- vided with 'an objective A, a collective B for theobjective, an erecting system C, cross hairs or sighting mark D, and aneyepiece E. In order'that the objective end of the instrument may lieout of alinement with the eyepiece end the casing of the telescope isformed of a plurality of arms at the junction of which are arrangedprismatic reflectors F and G. In this instance the member of the casingof the telescope carrying the objective comprises a hood 1 preferablyhaving threaded engagement with the prism carrying elbow 2 to which isconnecteda tuT bular section 3, the connection being established by acollar 4 screw threaded on the section 3 and having a flange 5 connectedto a flange 6 on the elbow 2 by bolts 7.

" may 1,01 na ls" screws Maud fit operable from we exterior of theenlargedport1on and cooperating with dental operation of theseadjnstiiig screws and 54 and also screws 53 may be presented bysurrounding the enlarged portior by a casing 55 provided wi h open Lings 56 and 68. This casing may be rotated on screw threads '57 to cannythe openings 56 over the screws 54 and $411 and openings' 68 over screws53, or may be shifted to throw said openings away from the screws so.that the latter cannot be operated. The

casing 56 may be held against movement by a loch screw 55 workingin,.-t'he slot 58 in the casing andengaging theenlarged flangel2 of theenlargement of thetube.

To the end that the cross hairs may :be

rotated the tube 43 is surrounded by a ring or cox 59 Which s connectedwith the carrier a? by means of, a projectioii 60 extend ing outwardlyfromthe carriers 17 through a circumferential slot 61 1n;the tube 43."

?referably the ring 59 has-a elongitudinal roove'SEZ into which thePTOJQQUOH 60 exgroove 66 a"nd locking the ring against The periphery oithe ring 59 also be provided with transverse grooves 67 adapted to bealined with the openings 68 in the casing so that the screws 58 may beadjusted.

The operation of the instrument will be apparent to those familiar w'ththese de vices, but it may be stated generally that the bracket 68 issecured to either side of the gun at an angle of about 45 the crosshairs being shifted to correspond to the adjustment and being axiallyalined with the optical axis of the instrument. .The eyepiece isadjusted to correspond to the eves of the user by operating clampingjaws 3? to free and then to grip the tube 34.

it is apparent that all the optical parts are rigidly secured againstaccidental adjustment due to the firing of the gun. The rotation of thecross hairs permits the intrun ant to be arranged on either side of .L1(511H and in anv operative position; and the relative lateral adjustmentbetween the arms of the telescope prevents straining of the jointbetween the arms.
